Power Xpert Branch Circuit Monitor
■For use with PXBCMPower Xpert Branch Circuit Monitor-The PXBCM–MME Meter Module External (MME) is designed to be used with the following PXBCM components to form an electrical metering system:
▲PXBCM-MB-(BASIC/ENERGY) Meter Base
▲PXBCM-MMS-(L/R 9/15/21)-A Meter Module Strip
▲PXBCM-MMP-CBLnn/-CBLEnn Meter Module Port Cable and Cable Extension
■The PXBCM-MME-X25-333MV and PXBCM-MME-X21-100MA (MME) is designed primarily for retrofit or high mix panel board applications.The MME provides metering inputs for up to 21 exter-nal 333mV or 100mA Current Transformers (CT) and 4 AX auxiliary 333mV CTs.These can be split into Three or Single phase voltage measurements.The separate PXBCM-MB-BASIC or PXBCM-MB-ENERGY Meter Base provides power to the MME and shares data through the Meter Module Port and PXBCM-MMP-CBL-nn cable.
■The PXBCM-MME must be housed in an appropriate NEMA or UL enclosure that ensures the device will remain within its specified environmental ranges and provides fire and mechanical protection.In retrofit panel board applications,the MME must be mounted in an enclosure external from the monitored assembly gear,unless the MME is an approved accessory for the panel board.
■Each Meter Module External has the following LED Indicators
▲MMP Meter Module Port coms-Bicolor LED
◆Rx/Tx Green/Red
▲Status - Green LED
◆~1Hz blink–Normal heart beat
■Terminate the secondary of up to 21,333mV or 100mA external CTs,rated for the application,to the CT terminal blocks on the MME.These are dual-tier terminal blocks,with the back/high tier for positive X1 inputs (typically white) and the front/lower tier for the negative X2inputs (typically black).The terminal pairs are numbered adjacent to the terminals.Terminate the secondary of up to four,333mV external CTs,rated for the application, to the Auxiliary AX terminal blocks.The termination is set up similar to the CT circuits but are located on the opposite side of the MME.The typical use case is to monitor the panel main circuit cables. External CTs must provide basic isolation between primary load cables to secondary output, qualified to:
▲UL/IEC61010-1
▲UL2808
▲UL/ANSI C57.13
▲IEC 60044
■The VT Voltage Terminal block on the bottom right of the MME pro-vides metering inputs to monitor the modules load mains connec-tions.Phase A,B,and C inputs should be equipped with fuses or breakers sized to protect the wiring and provided with a disconnect.
